Application November 16, 1931, Serial No. 575,214 11 Claims. (01. 2 3-77) The main objects of this invention are:
First, to provide animproved metal golf club head which can be very economically manufactured in desired shapes, sizes and weights.
Second, to provide an improved golf club head made mainly of stampings welded or brazed together.
Third, to provide a metal golf club in which the desired shape and weight can be readily attained and the weight centered as desired with very uniform results and without machining.
Objects relating to details and economies of my invention will appear from the description to follow. The invention is defined and pointed out in the claims.
A structure which is a preferred embodiment of my invention is illustrated in the accompanying drawings, in which:
Fig.v 1 is a front elevation of a golf club head embodying my invention.
Fig. 2 illustrates the sheet metal blank of the main part of the head and hosel.
Fig. 3 is a view similar to Fig. 2, showing the stamping after the first forming or drawing operation.
Fig. 4 is a transverse section taken on line 44 of Fig. 3.
Fig. 5 is a transverse 5-5 of Fig. 3. I
Fig. 6 shows the stamping after the flange on the head portion has been trimmed and the hosel closed.
Fig. '7 is a perspective view of the face plate.
Fig. 8 is a transverse section taken on line 8-8 of Fig. 1.
Fig. 9 is a front elevation of the face plate having the insert or filler seated in its opening.
Fig. 10 is a transverse section taken on line 10-10 of Fig. 1. Y
Fig. 11 is a top plan view of the insert or filler.
Referring to the drawings, numeral 1 indicates a sheet metal blank which is cut to the shape indicated for providing a hosel or shaft socket portion 2 and a head portion 3. The blank 1 is subjected to a forming operation whereby the hosel portion 2 is given the channel shape, as indicated by Fig. 5, and the head portion 3 is given the spoon shape, as indicated by Figs. 3 and 4, with the flange 4 extending around the periphery of the head portion anddisposed in a single plane.
In the next operation, the outer edge 5 of the flange 4 is trimmed off along the dotted line 6 (Fig. 3). The flanges 7 of the hosel portion are then folded inwardly to form the seam 8 section taken on line which is welded or brazed together, preferably so as to substantially conceal the seam. The resultant element is illustrated in Fig. 6, the hosel being now ready toreceive the shaft.
The face plate 9 having opening 10 therein is next welded to the flange 4 as indicated at 11. The rim of the face plate 9-and the edge of the flange'4 are substantially flush or contiguous so as to present, a solid appearance. However, before the .face plate 10 is positioned and welded to the flange 4, the die cast white metal insert 12 is assembled with the face plate 9 so that the raised'impact member or face 13 of the insert is seated ,in andfills the opening 10 in the face plate. The surface of the impact member 13 and the surface of the face plate' soccupy substantially the'same'plane as is illustrated by Fig. 8. The body of the insert 12 preferably fills the head in the embodiment illustrated. It is to be understood, however, that the insert or filler may be of any desired shape or size to secure the desired weight and to properly center the weight.
The striking face of the insert illustrated is provided with a plurality of spaced indentations 14. The face may be shaped as desired as the desired formation may be easily attained by die casting.
Some of the advantages of a golf club head constructed in accordance with my invention are that the weight can be accurately controlled and centered without machining, and a head of larger dimensions and substantially any shape may be made without excessive weight and pro duced much more economically than forged heads in which there is a considerable variation in weight. Furthermore, the head is simple and may be made economically because of its practically entire sheet metal construction.
It is obvious that various changes and modifications may be made in the details of construction and design of the above specifically described embodiments of my invention without departing from the spirit thereof, such changes and modifications being restricted only by the scope of the following claims.
Having thus described my invention what I claim as new and desire to secure by Letters Patent is:
1. A golf club head comprising a sheet metal cup-like flanged rear portion having a hosel integral therewith, a metal face plate rigidly secured to the flange of said rear portion and having an impact member opening therein, and a die cast metal filler disposed within said head an impact member sheet metal h a hosel and comprising a holhaving a peripheral flange, a

d a die cast inser rtion dispose lub comprising a sh like head portion having an in flange eaten a single plane, sai tegral tubular hose secured to said plate being flush w cling around its 1' and a metal filler disposed within said spoon-like head portion in supporting engagement with the face plate.
'7. A golf club head comprising a sheet metal spoon-like head portion having an integral flange extending around its rim, a metallic face plate welded to said flange and having an impact member opening, and a filler disposed in said head portion and having a raised impact member filling said opening.
8. A golf club head comprising a spoon-like head portion having an integral flange extending around its rim, a face plate welded to said flange and having an impact member opening, and a filler disposed in said head portion and having a raised impact member filling said opening.
9. A golf club head comprising a cup-like flanged rear portion, a face plate rigidly secured to the flange of said rear portion and having an impact member opening therein, and a filler disposed within said head and having a raised impact face fitting the opening in said face plate.
ll). A golf club head provided with a hosel and comprising 'a hollow body portion, a face plate fixed tosaid body portion and having an opening therein, and an insert disposed within and filling said hollow body portion and provided with an impact face disposed in the opening in said face plate.
